Problems solved by technology

[0002] The existing end-fired antenna array achieves a polarization parallel to the plane where the antenna is located. If vertical polarization is to be provided, the antenna needs to be perpendicular to the floor, which occupies a large antenna height and seriously affects the aesthetics and concealment of the antenna.

Abstract

The invention provides a magnetic monopole end-fire antenna array with low profile, wide frequency band and good directivity, including antenna unit, microstrip transmission line, microstrip feeder line, dielectric plate and floor; said antenna unit, microstrip transmission line , the microstrip feeder and the floor are printed and processed on the dielectric board; the antenna unit includes two pairs of magnetic monopole units symmetrically placed on both sides of the microstrip feeder to form two pairs of symmetrical array sources; each magnetic monopole unit passes through the micro The strip transmission line is connected to the microstrip feeder line, the excitation source of the antenna array is the excitation of the radio frequency port, and rectangular slots are symmetrically opened on both sides of the floor. The antenna is in a flat state, which can realize the polarization characteristics perpendicular to the plane where the antenna is located, has a very low application height, can improve the aesthetics and concealment of the antenna, and has good frequency bandwidth and directivity.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a magnetic monopole end-fire antenna array. Background technique [0002] Existing end-fire antenna arrays achieve polarization characteristics parallel to the plane where the antenna is located. If vertical polarization is to be provided, the antenna needs to be perpendicular to the floor, which occupies a large antenna height and seriously affects the aesthetics and concealment of the antenna. Contents of the invention [0003] The present invention provides a magnetic monopole end-fire antenna array to overcome at least one defect (deficiency) described in the above-mentioned prior art. Wide frequency bandwidth and good directivity. Most importantly, the antenna can realize the polarization characteristic perpendicular to the plane where the antenna is located. When the antenna is to provide vertical polarization characteristics, the antenna is in a flat state and has a very low ap...
